View A Historical Article About The Previous Bridge

This bridge is an example of a typical cantilever through truss using a style that the Washington Department of Highways preferred. The distinctive cantilever style differs from those commonly found in other states in that the pointed towers above the roadway are eliminated by locating the extra truss depth required at the piers to below the deck.

Previously at this location was a ferry and a railroad bridge built in 1897 for the Red Mountain Railroad Company. The railroad bridge was later converted for highway use, and used until the bridge deteriorated and was closed on October 5, 1946. It apparently later collapsed. Originally, the bridge was only going to have three t-beam approach spans, but flooding during construction revealed that it would be wise to add five additional t-beam spans. The bridge was built for $1,751,587 and opened on June 13, 1951.

MacRea Brothers were the contractors for the original approach spans and bridge substructure while General Construction Company was the contractor for the added t-beam approach spans and reconstruction of the south main pier which was also damaged by the flood during construction. Midland Structural Steel Company was the superstructure contractor.
